Specification of Letters Patent.

Patented Nov. '7, 1905.

Application filed February 17, 1905. Serial No. 246,076.

To all whom it may concern.-

Be it known that I, SVEN CARLsoN, doctor of philosophy, a subject of theKing of Sweden and Norway,residing at 93 Valhallavagen, Stockholm,Sweden, have invented new and useful Improvements in Petroleum-Burners,of which the following is a specification.

This invention relates to petroleum-burners, and has for its object toconstruct such burners so that the flame will be uniform or eventhat isto say, that its upper edge will terminate in a horizontal plane.

In the accompanying drawings, Figure l is an elevation of a burnerembodying my invention. Fig. 2 is a vertical section, and Fig. 3 ahorizontal section,of the same. Fig. 4 is a vertical section along oneside of the burnertube.

a is the tube through which petroleum ascends to the annular vaporizerF), from which the vapor passes through the tubes 0 to the nozzle 03,from which latter it passes subsequently upward through the tube 6 andbecomes mixed with air for the combustion, whereupon the mixture onstriking the plate or cover f is compelled to turn downward and finallyescapes through slits g in the surrounding casing it. Now thisconstruction of burner is already known, and I do not claim same; but myinvention consists in that the slits g in place of being straight, asheretofore customary, are so curved that their middle portions aresituated higher than their ends. It has been found that the vaporescaping through these slits on ignition will form a flame which isperfectly uniform or even, the distance to the upper edge of the flamebeing smaller from the middle of each slit than from the ends. The upperand lower edges of the slits are preferably inclined upward, as shown inFig. 2, in order to facilitate the upward flow of the mixture.

The burner is applicable for both heating and lighting purposes.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is* A hydrocarbon-burner consisting of an upright tubeprovided with separate slits whose walls extend in planes inclinedupward from the axis of the tube, the middle portions of the slit beingslightly higher than the end portions.

in testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

SVEN CARLSON.
